2 Claims. (Cl. 41-33) My invention relates to casings formed from be Setforth in the following specification, referanimal intestines which arecustomarily filled ce being had to the accompanying drawing, and

with meat of various kinds to form sausages, bothe novel means by whichsaid objects are effeclognas, and the like, and more particularly to atuated will be definitely pointed out in the claims.

In no 50 These and further ob ects of my invention willcase, however, is the tem erature. to which the Cellophane and intestinecasing are subjected, permitted to rise above the boiling point.

During the foregoing action, it is supposed that the brine solution onthe intestine casing either dissolves, loosens, or splits the waterproofcoating on the Cellophane which carries the design and that in somemanner, the

I design thereafter becomes affixed to the casing itself. It will beunderstood, however, that the precise nature of the action is notthoroughly understood, but whatever happens, the design does transferfrom the Cellophane sheet to the intestine casing, so that it isthereafter possible to strip the casing from the pipe 10, with thecomplete design aflixed thereto. The Cellophane sheet that has been usedmay then be disposed of in any manner.

In- Fig. 2 is illustrated a further modification of the method whichmore particularly refers to the double type of casing. In this case, thenumeral 13 indicates a round stick having a longitudinal groove 14,which is of the general type now employed in the casing industry for themanufacture of double or sewn types'of casings. When using this stick, acasing 15 will first be drawn thereover, a printed sheet 16 ofCellophane will be applied to the surface of the casing 15, andthereafter a second casing 17 is drawn over the Cellophane sheet andcasing 15.

In this instance, the stick 13 and its associated casings are exposed toa steam bath, or any other desired form of heat, the heat being appliedexternally, and the temperature maintained below the boiling point,until, as determined by the inspection of the operator, it has beenascertained that a satisfactory transfer of the design to the innersurface of the casing 17 has been attained. Thereafter, the casing 17may be slipped back sufficiently to permit the withdrawal of theCellophane sheet, after which both casings may be withdrawn together. Ifit is desired to make a sewn type of casing, then, upon the completionof the transfer step of the method, a knife is inserted in the groove 14and drawn along the stick 13 to completely sever the concentric casings15 and 17, in order to form a pair of superimposed sheets.

may be extracted for subsequent disposal.

Thereafter, a second pair of casings may be drawn over the stick 13 andslitted, as is well known in the art, for subsequent attachment to theslitted casings 15 and 17 by sewing.

In Fig. 3 is illustrated a filled casing 18 with a. portion 19 thereoflifted to expose the design affixed to the interior surface thereof. -Inthe double type of easing, this design would be afiixed either to theinner surface of the outer casing, or to the outer surface of the innercasing, as the choice of' the operator dictates. Owing to thesemi-transparent condition of the casing, it will be obvious that thedisposition of the indicia on the inner surface of the casing does notinterfere with its easy observation. Moreover, the design is protectedfrom abrasions, due to handling, and also against surreptitious removal.

The reference to Cellophane as being the preferred material to use ineffecting a transfer ofthe indicia is not to be restrictively construedas it is obvious that other materials having equivalent characteristicsmay be employed without departing from the spirit of the invention asdefined in the appended claims.

I claim:

The method of applying indicia to an animal intestine, sausage casingwhich consists in applying to the surface of a moist casing a sheet ofCellophane bearing the indicia, and subjecting the sheet and casing toheat to thereby effect a transfer of the indicia to the surface of thecas- 2. The method of applying indicia to an animal intestine, sausagecasing which consists in applying a sheet of Cellophane bearing theindicia to the surface of an arbor, drawing a moist casing over thearbor and sheet, then exposing the casing and sheet to a heating agentto thereby effect a transfer of the indicia to the surface of theeasing, and thereafter removing the remainder of the Cellophane".
